How to make a shooting range from scratch in Maya 2018?

[NikhilVibhakar]

I've just started using Maya 2018 and so far have created a shotgun at a very basic level just by extruding a cube. 

I want to make a shooting range but I do not know how to make one. Can someone help me since I cannot find any youtube tutorials.
